NEXTorr® and Capacitorr®: The ideal pumps for your Surface Science system What is the NEXTorr pump The NEXTorr is a combination of a NEG pump (NonEvaporable Getter) with a small SIP (Sputter Ion Pump), overall delivering excellent pumping performances for the typical gas composition in UHV systems The NEG element features high pumping speed particularly for H2, which is the main residual gas at UHV pressures The SIP can pump Methane, Argon and the other noble gas species, and also provides pressure reading The NEXTorr is an extremely compact pump: its weight ranges from 2.2 to 6.5 Kg! (depending on the pump model) Why the NEXTorr pump The NEXTorr is extremely compact! Space can be saved and used for other components (optics, detectors, …) 100 l/s sputter ion pump The NEXTorr (SIP+NEG), compared to the conventional combination SIP+TSP, features the following advantages: it does not need frequent reactivations it's more compact it does not create Ti flakes Ideally suited for surface science equipments like XPS, UPS, STM, SPM, AFM, AES, ARPES, LEEM/PEEM, LEED, (HR) EELS, XANES NEXTorr D 100-5 www.saesgroup.com making innovation happen, together NEXTorr® and Capacitorr®:The ideal pumps for your Surface Science system NEXTorr and CapaciTorr in STM system pressure level in STM chamber below 10-10 Torr (pressure indication by NEXTorr SIP) pressure level in the ESD chamber close to 10-10 Torr the NEXTorr D-200 is the only pump present in the STM chamber Courtesy of University of Hamburg (Dr. Bazarnik, group of Prof. Wiesendanger) back front After using NEG pump, the H2 features close to the Fermi Level disappeared!

It’s a compact combination of a SIP featuring 10 l/s for Ar and 20 l/s for CH4, and of a NEG featuring 1000 l/s for H2. It’s only 6.5 Kg weight including the magnets! There is nothing to re-flash every few hours (no more TSP!). Dimensions in mm The Capacitorr® family If you already have your own SIP installed but you’re not satisfied of your Pressure…. Add a Capacitorr to your existing pumping system! The Capacitorr is a NEG pump boosting your pumping performance for H2 (main residual gas at UHV pressures). Does not need any power for operation (after the activation). No more Titanium flakes around! No need of frequent reactivations (can stay for years at 10^-10 mbar!)
